Ignition Coil: Testing and Inspection

1. With the ignition switch OFF, remove the ignition coil.
2. Using an ohmmeter, measure resistance between the terminals. Replace the coil if the resistance is not within specifications.

NOTE: Resistance will vary with the coil temperature; specification is at 77° F (25° C).

Primary Winding Resistance
(Between the A and B terminals): 0.9-1.1 Ohms

Ignition Coil Test:

3. If primary winding resistance is OK, substitute a known-good ignition coil, and check the system operation.

If the system is normal, replace the original ignition coil.
